Analytical know how on packaging materials

Analytical know-how on packaging materials:

Having both classical recognized analytics like HS-GC/MS and a sensor system in parallel led to better understanding of the analytical methods for the latter technique in respect to printing materials. It was showing that a separation of organic solvents and water is necessary in order to have comparable results as a certain cross sensitivity with water is still given for the sensors. And in case of printing materials water isn't a minor component. Finally, the separation is managed by a packed column with a special phase in isothermal mode. But already with direct methods different printing techniques can be differentiated as shown in a early project stage.
